What is Freeze Drying ? What does Freeze Dryer do?
Climate change, population growth and global warming have been playing a spoilsport in fresh food supply and have resulted in huge imbalance of demand and supply of fresh food. Discussions around food and preservation have become center stage and preserving food has become the mainstay of any economy. Different forms of food drying are being carried out to preserve food. However, freeze drying remains the gold standard within food preservation mechanisms.
A Freeze Dryer, also known as a freeze drying machine, eliminates moisture from perishable products to preserve them, prolonging their shelf life and facilitating transportation. The Freeze Dry process involves freezing the material and subsequently lowering the pressure while introducing heat, causing the frozen water within the material to transform directly into vapor through sublimation.
Different Phases in Freeze Drying
Phase 1: Freezing or Ice Make Stage
- In the initial stage, the product is subjected to freezing temperatures ranging from -20 to -30°C.
Phase 2: Primary Drying (Sublimation)
- During the second phase, known as primary drying or sublimation, the material undergoes a reduction in pressure, accompanied by the application of heat, facilitating the sublimation of water from the material
Phase 3: Secondary Drying (Adsorption)
- In the last stage, known as secondary drying or adsorption, the water molecules that are ionically bound are eliminated.

Q & A
Is Freeze Dryer the same as Dehydrator?
A freeze dryer freezes food at very low temperatures and then removes the ice by sublimation. This means that the ice transitions directly from a solid to a gas without becoming a liquid. This process preserves the food’s structure, taste, and nutrients exceptionally well. Since freeze dried foods can be rehydrated easily into original form, they are extremely popular as convenience and packaged foods.
On the other hand, a dehydrator removes moisture from food by circulating warm air around it. This process is simpler and less expensive than freeze-drying, but it may alter the food’s texture, taste, and nutrient content more than freeze-drying does. Dehydrators are commonly used to make snacks like chewy dried fruits, jerky, and fruit leather.
How is Freeze Dryer different than Vacuum Dryer?
As against vacuum dryer wherein food is dried at low temperatures (close to room temperature), a freeze dryer preserves food by drying it at a sub zero temperature.
Is Freeze Dryer a Food Dryer ?
Yes. Food dryers include many other types of dryers, like solar food dryers, vacuum dryers, heat pump dryers, spray dryers, and freeze dryers. Globally Freeze Dryer is considered as a gold standard within food drying machines due to the rehydration capabilities and nutrition retention it offers for the products dried through it.
Why should you NOT buy a Freeze Dryer ?
Freeze-drying is expensive. Equipment costs and operational costs are high as compared to other forms of food drying methods. However, if rehydration capability, nutrition retention, aroma, and flavor are of importance to your product, there is no better alternative to freeze drying.
What is the price of a freeze dryer?
Freeze dryer prices in India depends on the processing capacity that the client wants for specific products. Once the client shares the specific product(s) and the processing capacity that he needs per day along with the budget that he has, we suggest the best freeze drying solution that he can get from us. For clients who are open to purchasing used or second-hand freeze dryers, we provide them with refurbished freeze dryers tailored to their food products manufacturing requirements. The price of a refurbished lyophilizer is lower that that of a new freeze dryer.
Why haven’t we listed the price of freeze dryers?
Except Home Freeze Dryers which are standard models with standard pricing for us, none of our industrial and commercial freeze dryers are standard models. For us each requirement is unique and we treat it accordingly. A 50 Kg freeze dryer for a client looking to freeze dry strawberries will have different spec’s and dimensions than a client looking to freeze dry 50 Kg ready to eat/cooked meals.
As a first step in fulfilling the requirements of our customers, we take details regarding product that is to be freeze dried, daily input capacity that is to be fed in the freeze dryer and most importantly, the budget that the client has to set up a freeze dryer. Basis these 3 details, we suggest the best freeze drying solution that we can offer to the client, either in the form of supplying a new freeze dryer or a refurbished freeze dryer.
